Steel Division: Normandy 44
Seems Paradox Interactive, (known for games like Hearts Of Iron, Stellaris, are creating a new RTS that takes places in WW2:
Steel Division: Normandy 44 is a Tactical Real-Time Strategy (RTS) game, developed by Eugen Systems, the creators of titles like Wargame and R.U.S.E. This new game puts players in command of detailed, historically accurate tanks, troops, and vehicles at the height of World War II. Players can measure their tactical skills against several opponents in big multiplayer battles or against enemies in a challenging single-player campaign. Steel Division: Normandy 44 allows players to take control over legendary military divisions from six different countries, such as the American 101st Airborne, the German armored 21st Panzer or the 3rd Canadian Division, during the invasion of Normandy in 1944.
Looks mighty interesting!
